Level II / Anomaly Scan: Detailed Fetal Assessment
The Level II / Anomaly Scan is an advanced prenatal ultrasound performed during the second trimester (usually between 18–22 weeks) to provide a detailed assessment of fetal organs, growth, and overall development. It is often referred to as the anomaly scan because of its focus on detecting congenital anomalies.
What Is a Level II / Anomaly Scan?
This scan provides a comprehensive evaluation of your baby, including:
- Brain and spinal cord structures
- Heart chambers, valves, and major vessels
- Lungs and diaphragm
- Kidneys and urinary tract
- Limbs, hands, and feet
- Face and neck structures
- Abdomen, including stomach, intestines, and umbilical cord
- Placenta, amniotic fluid, and umbilical cord blood flow
Unlike earlier scans, this detailed evaluation helps identify structural abnormalities and assess whether the baby is growing normally.
Why Is a Level II / Anomaly Scan Important?
1. Detailed Structural Assessment
It can detect congenital anomalies, including heart defects, cleft lip, kidney malformations, and skeletal abnormalities.
2. Monitoring Fetal Growth
The scan evaluates whether the baby is developing proportionately and whether the amniotic fluid and placenta are healthy.
3. Planning for Birth
Early detection allows doctors and parents to prepare for interventions or special care after delivery if needed.
When Is the Level II / Anomaly Scan Done?
- Ideal timing: 18–22 weeks of pregnancy
- Before 18 weeks: Organs may not be fully visible
- After 22 weeks: Some abnormalities may be harder to correct or plan for
How Is the Level II / Anomaly Scan Performed?
-
Abdominal ultrasound is standard; transvaginal scan may be used for better clarity in some cases
-
The sonographer examines:
- Detailed organ anatomy
- Placental location and function
- Amniotic fluid volume
- Fetal growth measurements (head, abdomen, limbs)
-
The scan typically lasts 30–45 minutes depending on fetal position and clarity.
Is the Level II / Anomaly Scan Safe?
Yes. It is a non-invasive and safe procedure for both the mother and baby, using ultrasound technology without radiation.
Who Should Get a Level II / Anomaly Scan?
- All pregnant women during the second trimester
- Pregnancies with previous complications
- Women of advanced maternal age (≥35 years)
- IVF or assisted pregnancies
- Family history of congenital anomalies
FAQs – Level II / Anomaly Scan
What is the purpose of a Level II / Anomaly Scan?
To perform a detailed assessment of fetal organs and growth, and to detect any structural abnormalities.
Is this scan different from a regular anomaly scan?
Yes. Level II is more detailed than the early anomaly scan, evaluating each organ system comprehensively.
Is the scan safe for my baby?
Yes. It uses ultrasound waves and is completely safe for both mother and baby.
Can this scan detect genetic conditions?
It primarily detects structural abnormalities, not genetic or chromosomal disorders. For genetic screening, tests like NIPT or NT scan are required.
Do I need to prepare for the scan?
A moderately full bladder is usually recommended for better imaging. Follow your doctor’s instructions for preparation.
Will the baby’s gender be identified?
Yes, if parents wish to know and if the baby is in a suitable position.
What happens if abnormalities are detected?
Further testing, specialist consultations, or follow-up scans may be recommended to assess and plan care.
How long does the scan take?
Typically 30–45 minutes, depending on fetal position and visibility of organs.
Conclusion
The Level II / Anomaly Scan is a crucial step in prenatal care, ensuring detailed monitoring of your baby’s growth and organ development. Early detection of anomalies allows for timely medical advice, proper planning, and reassurance for parents.
